Power Management in Complex Multi-Physics Systems
This talk is motivated by a long term trend regarding mobile systems such as aircraft, on-highway vehicles, off-highway vehicles, marine vehicles etc. There is a steady increase in the level of electrification within these systems both in terms of overall electrical power as well as power density. The increase in electrical power density is limited by the ability to manage the thermal power resulting from inevitable system inefficiencies. The focus of this talk is on the overall management of power flow, in multiple physical modalities (electrical/thermal).
We present a particular hierarchical approach to power flow that accommodates multiple power modes. The hierarchy allows for systems operating on different time scales to be coordinated. It also allows for different dynamic decision making tools to be used at different levels of the hierarchy based on the needs of the physical systems under control. Recent analytical and simulation results will be presented representing both generic interconnected complex systems as well as specific examples from industrial partners.
